WORK-EJECTING MECHANISM FOR PRINTING- APPARATUS.

Application lnea March a, rats. Serial in. 258,770.

Ihis invention relates to mechanism acting automatically to discharge a printed product following the impression stroke. The invention is particularly well adapted for embodiment in an addressing machine employing individual address 'plates and a manually operable platen. When so embodied, it includes a device carried by the platen arm and serving to engage the paper on the printing stroke of such arm and remaining in engagement during a portion of the reverse stroke of the arm and at that period having a movement relative to the arm to eject the printed work. The invention is hereinafter more fully described in connection with a preferred embodiment illustrated in the drawings.

Fig. 1 is a plan of an addressing machine embodied in my invention Fig. 2 is avertical transverse section of the same on the line 2 2 of Fig. 1; Figs. 3 and d are views of P the platen arm and discharge control mechanism shown in Fig. 2, but in diiferentpositions; Fig. 5 is a front elevation of the ejecting mechanism in the position shown in Fig. 4; Fig. 6 is a detail in vertical section on the line 6-6 of Fig. 5; Fig. 7 is a perspective of the rocking frame carrying the paper engaging members; Fig. 8 is a perspective of a bracket towhich the rocking frame is pivoted; Fig. 9 is a side elevation of the lever and latch controlling the rocking frame, on

a larger scale than the two preceding figures; g

iFig. 10 is arr-edge view of the parts shown in In the embodiment shown in the drawings, 10 indicates the bed of frame of a fiatbed addressing machine. Extending transversely across this frame is a channel 11 along which the address plate may travel from a magazine 12 to printing position, after which it'is discharged at the left hand side of the machine.

A manually operated impression arm 20' is shown in the drawings as pivoted to the bed while.

at 21 adjacent the rear end of the arm at the forward end'is an operating handle 22, and a short distance behind the handle is a platen adjustably carried by the arm'in the usual manner.- The impression arm 20 is normallymaintained elevated as shown in "Fig. 2; by a'suitable spring or springs 25 attached to rear extensions of the arm. The

rear extension 26 is connected by a-suitable system of linkage 27 with a reciprodating as slide 28 in the channel' 11. r

As the arm 20 is depressed to effect, the printing, by means of a plate directly below the platen 30, the slide 28 is carried toward the right so that the bottom-most address so plate A, Figs. 1 and 2, may drop from the magazine 12 onto the slide in front of a shoulder thereon; then as the platen moves upwardly, the linkage mechanism described moves the slide toward the left carrying the o5 bottom-most plate from themagazine into position immediately at the left thereof. The same movement carries the plate which has just been printed from by the platen into a receptacle 29 at the extreme left of 7c the machine, and at the same time carries an intermediate plate which was standing at the left of the magazine into printing osition beneath the platen.

It will be seen that the mechanism and operation above described are well known in addressing machines, and such machines have frequently been employed with the envelopes or cards addressed thereby removed manually following each impression. it is so desirable however, to provide automatic means'efiecting the discharge and that is one of the purposes of the present invention. The card or envelope is placed by hand heneath the platen, if desired against a suitable uide 15 carried by the bed, and remains in the down stroke of the platen. With my ejecting mechanism, which will now be described, as the platen is beginning its upstroke, ried by the impression arm and engaging the rinted envelope or card, suddenly moves forwardly and thus ejects the work from the machine.

As shown' in rigidly to the operatin arm 20 a suitable bracket 40 (shown deta'c ed in Fig. 8 which has a portion 41 resting on top of ,t e arm, an. upwardly extending ear 42 and a pair of downwardly extending ears this position on ing ears is a rocking frame 50, s own 'detached in Fig.

mediately plate-like portion 52, the ends of which terminate'in the side wings 54 by 15 which the frame: is pivoted. The intera suitable device carthe drawing, I have secured 7 This framehas' an .intermediate portion 52 is shown as flanged rearwardly at the top at 55 and as having rearwardlyfianged ears 56 at the bottom. Slidably mounted in the ears 56 and the? flange 55 are a pair of vertical plungers 60. Each plunger'has at its lower end a sleeve-like head 61 inwhich is mounted a projecting soft rubber plug 62. A compression spring 65 surrounds the shank of each plunger and is compressed between the flange 55 anda washer 68 resting on a pin in the plunger. Accordingly, the plungers have a tendency to move downwardly until the pins and washers are stopped by engaging the ears 56 of the swinging frames The swinging frame 50 is given a tendency to rock with its lower end toward the front by means of a spring 70 anchored at its lower end to a pin 71 on the swinging frame and at its upper end to the rigid bracket 40. The movement in this direction however, is limited by an arm 57 extending rearwardly from'the wings 53 and adapted to engage the upper surface of the rigid bracket 40. Movement in the opposite direction'is limited by an arm 58 on the wings 53 which is adapted to engage the under surface of the gverhanging portion 41. of the rigid bracket Pivoted at 81 to the upstanding ear 42 of the rigid bracket 40 is a lever 80.shown de 'tacheol in Figs. 9 and 10. The upper end of this lever is connected by a link 83 with arigid standard 84 on a frame. Pivoted at 85 to the lever 80 (that is below the pivot of the lever) is an arm which by means of ,a pair of ears 9lcarries a slidable latch pin 92. This pin is normally pressed downwardly by the spring 93 surrounding the pin and compressed between the upper ear 91 and a collar 95 on the pin.- The arm 90 is normally held against a pin 87 carried by lever 80 by means of a spring 97 anchored to the arm- 90 and the lever 80. The swinging frame 50 carries a shoulder with which the latch pin 92 coacts, as hereinafter explained. This shoulder'is shown as comprlsing a smalhbracket or a clip 59 rigidly attached to the wings 53 of the frame 50.

The relatively stationary bracket 40 carries a downward shoulder with which the upper end of one of the plungers 60 may coact, as hereinafter explained. As shown in Figs. 5 and 6. this shoulder comprises a screw 45 adjustable in the plate portion 41 of the bracket 40 and locked in the desired position by a jamb nut 46.

The position of rest of the parts above described is as shown in Fig. 2. In that case the impression arm 20 is 'held in its elevated position by the lifting springs 25 and the link. 83 holds the lever 80 tipped forwardly so that the lower end of the latch in 92 is at the rear of the shoulder 59 and ee from it. The spring 70 holds thero'cking frame 50 in the position shown in Fig. 2, the stop arm 57 engaging the stationary bracket plate 41. 3 i

It will be observed that the link 83 is materially shorter than the distance between the pivot 21 of the impression 'arm and the pivot 81 of the lever 80, with the result that as the impression arm 20 is lowered. the upper end of the lever 80 is-held back (travelling relatively rearwardly of the travel of its pivot 81) so that the lower end of the lever'80;carries the latch pin 92 forwardly into engagement with the shoulder 59, and thereby rocks the frame 50 into the position shown in Fig. 3. In this position, where the plungers 60 have become normalto the operation arm and stand parallel to the side of the platen, the movement is stopped by the arm 58 abutting the cross portion 41 of the bracket 40.

The above condition continues as the impression arm descends to effect the printing. Before theplaten 30 engages the address plate A the plungers 60 will have engaged the card or envelope B Fi 4, resting on the bed of the machine. lhis' stops the downward movement of the plungers butas the platen arm and platen continue their downward movement to print, .the frame 50 moves downwardly wlth reference to the plungers and this brings one of the plungers behind the head of the screw 45 as shown in Figs. 5 and 6. ;This looks the rocking frame 50 to the stationary bracket 40 preventing any swinging of the rocking frame. Almost immediately after the above locking has taken place, the latch pin 92 clears the shoulder 59; that is to say, the linkage and parts are so proportioned that as the platen arm 1s moving downwardly from the position shown in Fig. 3 to the prinitng position, the lower end of the pin 92 is travelling relatively upwardly along the forward end of the shoulder 59 and just after the plunger 60 looks with the screw 45, the pin 92 snubs off of the end of the shoulder 59 and the parts come into the position shown in Fig. 4. stant the printing is effected.

Following the printing impression, the impression arm and platen rise under the influence of the spring 25. In this movement the head. of the screw 45 prevents the frame 50 .from swi:n ing until afterthe platen has well clearef the paper, but when the platen has risen far enough above the paper for the frame 40 to have lifted enough forthe screw 45 to clear the plunger 60, then the spring 70 suddenly swings the released frame 50 forwardly while the soft lowerends of the plungers 60 are in engagement with the envelope. I The result is to snap the envelope forwardly and discharge it over the front of. the machine.

Following the discharge of the envelope.

This is the position at the ininto engagement with the top of that shoulder then to travel rearwardly along such top until it passes off of the same at the right hand end thereof and thus by reason of its spring 93, assumes the position shown in Fig. 3.

It will be seen from the above description that the action of my ejecting mechin their rearward position is coming intdprinting position,

anism is to cause the ejecting plungers to engage the envelope while the plungers are and just preceding the printing stroke, the plunger-s remaining in this position until after the impression; then, on the upstroke of the impression arm after the platen has freed the envelope, the frame carrying the plungers is allowed to swing suddenly forwardly, thus discharging the envelope or printed card at the front of the machine.
